AMP nucleosidase; AMP nucleosidase (AMN) catalyzes the hydrolysis of AMP to ribose 5-phosphate and adenine. It is a prokaryotic enzyme which plays a role in purine nucleoside salvage and intracellular AMP level regulation. AMN is active as a homohexamer; each monomer is comprised of a catalytic domain and a putative regulatory domain. This model represents the catalytic domain. AMN belongs to the nucleoside phosphorylase-I (NP-I) family, whose members accept a range of purine nucleosides as well as the pyrimidine nucleoside uridine. The NP-1 family includes phosphorolytic nucleosidases, such as purine nucleoside phosphorylase (PNPs, EC. 2.4.2.1), uridine phosphorylase (UP, EC 2.4.2.3), and 5'-deoxy-5'-methylthioadenosine phosphorylase (MTAP, EC 2.4.2.28), and hydrolytic nucleosidases, such as AMP nucleosidase (AMN, EC 3.2.2.4), and 5'-methylthioadenosine/S-adenosylhomocysteine (MTA/SAH) nucleosidase (MTAN, EC 3.2.2.16). The NP-I family is distinct from nucleoside phosphorylase-II, which belongs to a different structural family.

Bacterial AMP nucleoside phosphorylase N-terminus; This is the N-terminal domain of bacterial AMP nucleoside phosphorylase (AMNp). The N- and C-termini form distinct domains which intertwine with each other to form a stable monomer which associates with five other monomers to yield the active hexamer. The N-terminus consists of a long helix and a four-stranded sheet with a novel topology. The C-terminus binds the nucleoside whereas the N-terminus acts as the enzymatic regulatory domain. AMNp (EC:3.2.2.4) catalyzes the hydrolysis of AMP to form adenine and ribose 5-phosphate. thereby regulating intracellular AMP levels.

hopanoid-associated phosphorylase; The sequences in this family are members of the pfam01048 family of phosphorylases typically acting on nucleotide-sugar substrates. The genes of the family modeled here are generally in the same locus with genes involved in the biosynthesis and elaboration of hopene, the cyclization product of the polyisoprenoid squalene. This gene is adjacent to the genes PhnA-E and squalene-hopene cyclase (which would be HpnF) in Zymomonas mobilis and their association with hopene biosynthesis has been noted in the literature. Extending the gene symbol sequence, we suggest the symbol HpnG for the product of this gene. Hopanoids are known to be components of the plasma membrane and to have polar sugar head groups in Z. mobilis and other species.
